7.6 Guaranteeing the degree of protection of the measuring device
"
Caution!
Do not loosen the threaded fasteners of the sensor housing, as otherwise the degree of
protection guaranteed by Hauser no longer applies.
To guarantee the degree of protection of the measuring device.
Perform the following steps after electrical connection:
• Check that the housing seals of the connection and electronics compartment are clean and
fitted correctly. Dry, clean or replace the seals if necessary.
• Tighten all housing screws and screw covers.
• Firmly tighten the cable glands.
• To ensure that moisture does not enter the cable entry, route the cable so that it loops down
before the cable entry ("water trap") →  29.
• Insert dummy plugs into unused cable entries.
